1 oz of vanilla vodka
1 oz of Godiva white chocolate liqueur (or chocolate liqueur)
1/2 oz of blue curacao liqueur
Shake ingredients over ice, strain into a shooter glass. Add blue curacao slowly until the appropriate color is reached. You may need to add a little, shake, pour some to see the color, and then add more. A small amount of cream can be added if the shot is too blue.
